Sodium amide

Sodium amide is also called the amination of sodium, sodium or ammonia to white or olive green crystalline powder, the smell of ammonia, chemical formula NaNH2, molecular weight of 39.01, melting point is 210 ℃, boiling point is 400 ℃.
When heated to 500 ~ 600 ℃ is decomposed into sodium, nitrogen and hydrogen.
It works with water to produce sodium hydroxide and release ammonia.
Slightly soluble in liquid ammonia, it is slow to work with alcohol.
The rapid absorption of carbon dioxide and water in the air should be sealed and stored.
Liquid can dissolve metal magnesium, zinc, molybdenum, tungsten and quartz, glass, silicate and other substances.
An ionic compound formed by a hydrogen atom, which is formed by the removal of a hydrogen atom by a sodium and ammonia molecule.
It is flammable, explosive, corrosive and delirious.
Because the amino has the solitary electron pair, easily binds the proton, so encounters water strongly hydrolyzes, its aqueous solution is alkaline: NaNH2 + H2O = NaOH + NH3.
Soluble in liquid ammonia and hot ethanol.
Toxic dust.
Severe irritation of the skin, eyes and respiratory system.
Exposure to skin can cause corrosion damage.
It is used as an ammonia agent in organic synthesis;
Condensation accelerator;
Dewatering agent, dehalogen;
Polymerization initiator and the manufacture of hydrazine, sodium cyanide, azide, cyanide, hydrazine and indigo.
Amino sodium is easily oxidized in the air and produces a layer of yellow oxidation products on the surface.
Some of these oxidation products are explosive and may explode with friction or heat.
The amination sodium in a vacuum heating to 300 ~ 330 ℃, the decomposed into, sodium, hydrogen and ammonia nitrogen.
It is advisable to keep the storage in the bottle of inert atmosphere to avoid contact with air, water or fire so as not to burst into flames.
The sodium and carbon monoxide reactions can produce sodium cyanide, which can be used to make sodium cyanide.
Sodium aminosodium is used as an organic condensation accelerator, dehydrating agent, alkylating agent, etc.
Molten sodium and gaseous ammonia industry in 300 ~ 400 ℃ by amination reaction of sodium, the lab is by sodium and ammonia in the presence of catalyst reaction under normal temperature.
